From giant sea bass to spiny lobster and algae to sponges, kelp forests support some of the richest and most biodiverse marine ecosystems in temperate waters.
Kelp forest fish - effective number of species
Figure App.F.15.1.. A series of figures showing the equally-common species for kelp forest fishes (top), mobile bottom-associated invetebrates (middle) and deep water fishes (bottom) around the four Northern Channel Islands from 2005 - 2014.

Mean annual effective number of species for three taxonomic groups: kelp forest fishes (top), mobile demersal invertebrates (middle), and deeper water fishes (bottom). Shannon-Weiner diversity was converted to effective numbers of species, which allows for a more direct and intuitive comparison of community diversity over time. Kelp forest fish were surveyed across 86 shallow reef sites (3 to 16 meters depth) around the four northern Channel Islands from 2005 to 2014. Mobile invertebrates were surveyed across 63 shallow reef sites (3 to 16 meters depth) around the four northern Channel Islands from 1982 to 2016. Deep-water fish were surveyed at three reefs off the Channel Islands (Piggy Bank, Footprint, and Anacapa passage) at depths ranging from 40 to 407 meters in 1995 and annually between 1998 and 2011. Error bars indicate the 95 percent confidence interval in a given year. The horizontal line is the mean across sites over time.

Figure App.F.15.2.. A figure showing the temperature preferences for kelp-forest fish species across the four Northern Channel Islands. Anacapa and Santa Cruz Islands show a more southern (warmer) collection of fish species while Santa Rosa and San Miguel Islands have a more northern (cooler) collection of fish species.
